ClearComparision protocols for extraction of microplastics in water samples
Researchers compared four different extraction protocols for isolating microplastics from water samples and found significant differences in efficiency and accuracy across methods. Standardized extraction protocols are critical for producing comparable microplastic abundance data across studies. Without consistent methodology, it is difficult to build a reliable global picture of microplastic contamination levels in water.
